Military communication equipment observed at winter tests

Task Force “Frost” operations during the months of January and February 1947 at Camp McCoy, Wis., were observed by representatives of several companies. Purpose of the task force was to service test items of equipment under heavy winter and simulated combat conditions. Observations and recommendations for improvement of the equipment tested are included.

Discussion on "Thermal-Frequency-Drift Compensation" (by T.R.W. Bushby) [with author's reply

The design of military communication equipment must consider, among other factors, the effect of varying temperature on the equipment. The commentor feels that Mr. Bushby's article, although very opportune, omits the discussion of a very basic point to his whole article on page 548 where the premise of finding the smallest average drift factor θ over the frequency range is assumed. This criterion is not the most desirable condition. In replying, Mr. Bushby shows that the condition for minimum average drift factor (/θ/) throughout the range can be demonstrated geometrically.
